March 19, 2026 updated by: Gözde Nur Erkan

Comparison of Nasal Continuous Positive Airway Pressure (CPAP) Mask and Nasal Airway in Terms of Intraoperative Anesthesia Quality and Postoperative Associated Complications in Impacted Molar Tooth Extraction Patients Under Deep Sedation; A Multi-Center Study

In patients with high levels of fear and anxiety, it is recommended to perform dental procedures under sedation or general anesthesia depending on the nature of the procedure. In dental treatment under anesthesia, it is important that the procedure is comfortable and well tolerated by the patient. In addition, patient comfort is important in all dental procedures to prevent the development of avoidance behavior.

During dental procedures performed under anesthesia, the oral cavity is completely within the scope of the surgical or procedure field. In this respect, sedation and general anesthesia in dental procedures and operations have specific risks and challenges.Since there is a risk of respiratory depression, hypoxia and hypercarbia during deep sedation, non-invasive ventilation support provided to patients with airway devices would be beneficial. In the research clinics where the study will be conducted, deep sedation with non-invasive mechanical ventilation support using a nasal CPAP (Continuous Positive Airway Pressure) mask or nasal airway is applied during the extraction of impacted molars. Thus, many dental procedures are routinely performed under deep sedation without the need for general anesthesia. There are very limited data in the literature on the use of a nasal CPAP mask during sedation for different procedures in patients with obstructive sleep apnea or obesity. However, no study comparing ventilation support during deep sedation with nasal CPAP mask and nasal airway has been found in the literature.

The aim of this study is to compare the non-invasive ventilation support provided with 2 different airway devices during the procedure in terms of intraoperative and postoperative related complications, ventilation parameters, patient and surgeon satisfaction.

The hypothesis of the study is that two different ventilation support methods during deep sedation may be superior to each other in terms of anesthesia quality, postoperative complications related to airway devices, patient and surgeon satisfaction.

In the study, a total of 60 patients (Group airway, n;30, Group Mask, n;30) from 2 centers are planned to be included in the study by performing power analysis with a statistical power of the trial >0.8.

The permutation method will be applied within the scope of the restricted randomization method to determine the group of patients to be included.

Detailed Description

In the study to be conducted in two dental faculties, it is planned to use a total of 60 patient data, 30 patients with nasal CPAP mask and 30 patients with nasal airway. In the centers where the study will be conducted, deep sedation during dental procedures with ventilatory support via nasal airway and nasal CPAP mask, which will be compared in the study, is applied in routine practice. In this context, anxiolysis with 2 mg IV midazolam is administered to the patients before they are taken to the operating room on the day of the procedure. Patients are administered 1.5 mg/kg propofol and 0.5 mcg/kg fentanyl intravenously for sedation induction. Non-invasive ventilation support is then applied with a nasal airway or nasal CPAP mask and ventilation parameters are screened. Sevoflurane at 1 MAC (minimum alveolar concentration) level is administered inhalationally for sedation maintenance and the level of sedation is evaluated using the Ramsey sedation scale. Surgical dental extraction procedures between 20-60 minutes will be included in the study. For postoperative analgesia, paracetamol 1 g and dexketoprofen trometamol 50 mg are administered intravenously. The data planned to be collected within the scope of the study are blood pressure, heart rate, peripheral oxygen saturation (number of desaturation episodes), respiratory rate, ventilation parameters (Tidal volume (TV); set and actual, minute volume , end tidal CO2-EtCO2, and Peak pressure (Peak P). The total dose of agents used for sedation will also be recorded. During the post-operative follow-up period, the presence of nausea-vomiting, nasal pain, dryness in the nasal mucosa, epistaxis, sore throat, and dryness in the throat will be evaluated. Patient and surgeon satisfaction scores will be recorded.
